On the question...a runner completes exactly 2 laps around a 400 meter track...what is the distance and what is the displacement? Would it be...800m for distance and 0m for displacement? Thanks...

I agree

Idk. All I know is that I aint seen two pretty best friends

Does anyone know this question?

A runner at a track meet completes exactly two laps around a 400 m track.

a.What is the runner’s total distance covered?______________________

b.What is the runner’s total displacement?_________________________

I dont even know i went on this to get answers

Yes, you are correct! The distance covered by the runner would indeed be 800 meters because the runner completes 2 laps around the track, and each lap is 400 meters. To find the distance, you can simply multiply the number of laps (2) by the length of each lap (400 meters).

On the other hand, the displacement is given by the shortest path between the initial and final positions. Since the runner starts and finishes at the same position for 2 laps around the track, the displacement would be 0 meters. This is because the runner's ending position is the same as their starting position, meaning there is no displacement relative to the starting point.

So, in this scenario, the distance covered is 800 meters, while the displacement is 0 meters.
